This repository is archived due to our shift from building a zkEVM by writing custom circuits to developing a general purpose zkVM. You can read more about our direction shift in our blog: The next chapter for zkEVM Community Edition. We don't plan to continue the development and support of the zkEVM repositories at zkevm-circuits, zkevm-specs and zkevm-docs.

At the time of archiving this, the followings are some related developments that you might be interested in:

• The zkEVM-CE project was developed in collaboration with Scroll and Taiko. Scroll is still maintaining and updating their own version which you can find at scroll-tech/zkevm-circuits.
• If you are looking for a performant Keccak and sha256 circuits implementation, you can find the corresponding circuits originally developed for the zkEVM ready to be used in a halo2 circuit here axiom-crypto/halo2-lib thanks to Axiom who picked them and exposed them in a library.
• We're still maintaining and developing our halo2 fork at privacy-scaling-explorations/halo2
• We're still developing Chiquito at privacy-scaling-explorations/chiquito, a zk circuit DSL that implements many of the patterns found during the development of the zkEVM (mainly circuits described as a state machine).
